I want to describe the Order management API that has been implemented as part of
https://issues.ibexa.co/browse/IBX-5010

To do this, in the developer's guide, I will create an "Order management" subtree under the "Commerce" node. In this subtree I will create a markdown file with a description of the following methods: createOrder, getOrder, getOrderByIdentifier, findOrders, and udateOrder.

I will also prepare code samples to illustrate the functioning of said methods.
